Do you prefer the older mysterious unexplored style raids or the newer story focused raids?

Mysterious unexplored style raids: think AQ, BWL, ulduar. Raids that cover themes of WoW but take us to fight bosses that were shrouded in mystery to the player up until the point of the encounter.

Story focused raid: I'd say this started with ICC and gradually got more and more intense to today's DF raids where the antagonist plays a big role in the world ultimately leading up to the raid encounter.

Personally I like both but I do miss the sense of awe I got the first time my guild summoned ragnaros or walked into AQ. Newer raids have more build up to climactic moment though.
